San Francisco police are looking for Aldon Smith, the suspended Raider who's had a history of trouble with the law.

This time, he's wanted for questioning over a domestic violence incident in San Francisco over the weekend.

Smith was last seen proposing to his girlfriend at Gary Danko restaurant just last month. But on Saturday night, there appeared to be trouble between the two and now Smith is wanted for questioning over what exactly happened.

"It's the only way to get out," said building tenant Nikolaos Tzovolos.

Smith was a first-round draft pick by the 49ers seven years ago but was released from the team in 2015 after a string of arrests, the last one involving a hit-and-run.

He then joined the Raiders but was suspended for a year for a substance abuse violation. His trouble continued with a domestic violence investigation in Feb. 2017.

And as for this latest incident, police went to Smith's home in Oakland in hopes of finding him, to no avail.

The department is now seeking the public's help.

"Investigators are reaching out and are asking for the suspect, Aldon Smith to contact them, to arrange for an interview and of course if anyone out there knows his whereabouts we'd like them to also give us a call," said Sgt. Michael Andraychak of the San Francisco Police Dept. You can call them at (415) 575-4444.

As for Smith's fiancée, she told ABC7 she had nothing to say to the media, while the Raiders have not responded to our request for comment.
